Cubic boron nitride is a synthetic crystalline material second only to diamond in Knoop hardness. Although softer than diamond, CBN is superior in terms of abrasion resistance and oxidation resistance with steel alloys. Its relative crystalline inertness makes CBN the abrasive of choice for grinding steels, cast iron and nickel-based alloys.
Saint-Gobain Surface Conditioning's cubic boron nitride micron is designed for fine grinding and polishing in a variety of demanding surface finishing applications. The micron particles are graded to create a highly consistent PSD, with surface treatment and coatings to match the chosen bond technology.
